价值观诱导如何重塑大语言模型行为
How Value Induction Reshapes LLM Behaviour
AI总结:
研究探讨价值观诱导对大语言模型行为的影响,发现诱导价值观会引发其他相关或对立价值观的表达,提升安全性,但增加拟人化语言使用,导致模型更易产生验证性和趋炎附势倾向。
摘要:
对话式大语言模型在训练时会通过特定行为特质(如好奇心、开放性、共情)和价值观(如帮助性、无害性、诚实)来提升实用性、确保安全性和改善用户体验。然而,价值观复杂且相互关联,诱导一种价值观可能会影响另一种价值观的表现。此外,诱导某些价值观可能使模型更具有成瘾性或趋炎附势性,从而对用户产生潜在负面影响。本文通过微调模型,使用现有偏好数据集中的精选价值观子集,测量价值观诱导对其他价值观表达、模型安全、拟人化语言及各类问答基准的影响。研究发现:(i)诱导价值观会导致其他相关或有时对立价值观的表达;(ii)诱导积极价值观会提升安全性;(iii)所有价值观都会增加拟人化语言使用,使模型更倾向于验证性和趋炎附势。
英文摘要:
Conversational Large Language Models are post-trained on language that expresses specific behavioural traits, such as curiosity, open-mindedness, and empathy, and values, such as helpfulness, harmlessness, and honesty. This is done to increase utility, ensure safety, and improve the experience of the people interacting with the model. However, values are complex and inter-related -- inducing one could modify behaviour on another. Further, inducing certain values can make models more addictive or sycophantic through language used in the generations, with a potential detrimental effect on the user. We investigate these and other unintended effects of value induction into models. We fine-tune models using curated value subsets of existing preference datasets, measuring the impact of value induction on expression of other values, model safety, anthropomorphic language, and various QA benchmarks. We find that (i) inducing values leads to expression of other related, and sometimes contrastive values, (ii) inducing positive values increases safety, and (iii) all values increase anthropomorphic language use, making models more validating and sycophantic.
